DISINTEGRATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 793,506, dated June 27, 1905.

i Application filed February 18, 1904:. Serial No. 194,291.

To all whom it may concern.-

Be it known that I, ALBERT GEORGES AR- sNE CLRO, mechanical engineer, a citizen of the Republic of France, residing at 41 Rue de Rouelle, Parisin the Republic of France, have invented certain new and useful 'Improvements in Disintegrating Apparatus, of which the following' is a speciiication.

This invention has for its object improvements in disintegrating apparatus for materials of all kinds from the hardest to the softest, and in order that my said invention may be readily understood and carried into effect I will describe the same fully with reference to the accompanying drawings, in which Figure 1 is a vertical section of an apparatus embodying this invention; and Fig. 2 is a perspective view of the same, but drawn upon a smaller scale.

The apparatus consists, essentially, of a lower portion carrying the shaft c, of two heads t t', keyed upon the said shaft and rotating with it,and of beaters o of the form of cranked axles, which are journaled in the said heads In the drawings siX of these beaters are represented, but it is obvious that the number may vary according to the material to be treated and the result which it is desired to obtain.

The bottom of the apparatus is formed by curved plates l d', which are removably or interchangeably mounted and perforated in order that the disintegrated material may escape. These holes are of variable dimensions, in accordance with the degree of fineness which it is desired to obtain, and the particles which are too large to pass through these apertures are again acted upon by the beaters and reduced to the desired degree of fineness.

'Ihe aforesaid shaft a is supported in appropriate bearings o e', and upon each side are arranged driving-pulleys f f in order that driving effort may be equally distributed.

The upper portion of the apparatus is formed by a casing g and hopper L, through which the material to be treated is introduced in any suitable manner. The casing g is adapted-to pivot around the hinge e; for the purpose of facilitating the inspection and cleaning of the apparatus and also the replacement of the perforated plates and beaters.

The casing g being closed the shaft c is caused to rotate at a velocity which varies according to the nature of the material to be treated and the nature of the products which it is desired to obtain. rlhe beaters c under the infiuence of centrifugal force then assume a radial position with respect to the shaft et and in rotating upward with respect to the hopper L strike in their iight and throughout the entire width of the apparatus the material projected or introduced through the hopper. Assuming that there are six beaters and that the velocity is a thousand revolutions per minute, these beaters will make one hundred strokes per second, from which the irresistible force and enormous efliciency of this novel apparatus will be readily appreciated. Various materials may be treated together or they may be separated before treatment.

It should be noticed that the whole mass of the aforesaid heads b and of theV other parts mounted upon the shaft a act as a fly-wheel, and therefore assist the beaters, to the vis viva of which they add considerably. In addition to this, in view of the special method of mounting the beaters, which are loose with respect to the side pieces t, there is no danger of their breaking incase very violent shocks occur or of their causing too great strain on the other parts of the apparatus in which,

owing to this arrangement, all wedging is rendered impossible.

The rear face of the casing g is usually and preferably strengthened by means of bars g', in order that the material which is violently projected by the beaters may be still further broken up by coming into contact therewith and without injuring this wall.

In order to prevent wear, all the cast parts of the apparatus are constituted of a metal as resisting as possible, such as amiXture of iron and steel. The beaters, which are the onlyT parts of the apparatus exposed to wear, are preferably of untempered steel, and they are adapted to be replaced very readily. 'lhe various constituent parts of the apparatus may, however, be formed of any suitable material.

The power applied to the shaft ct will depend upon the hardness of the material to be treated and the results which it is desired to obtain. For hard materials-such as flint, schist, granite, quartz, and the like-and for an apparatus of ordinary dimensions the motor should supply from six to eight horse power per seventy-five kilogram meters.

rlhe products which pass through the perforated plates may be caused to fall directly into trucks or into sorting appliances, or they may be removed by conveyersl or in any other suitable manner.

Whatl claim, and desire to secure by Letters Patent of the United States, is-

In a -disintegrating apparatus, a rotary centrifugal beater comprisinga shaft, heads rigidly carried by said shaft for rotation therewith, and beater devices composed of cranked axles journaled upon the heads, combined with a casing for said beater, comprising a screen of curved form, forming the bottom of said casing, the upper part of the casing being hingedly mounted to obtain access to the beater and being provided with a hopper for the supply of material to the beater.`

In testimony whereoi` I have hereunto set my hand, in presence of two subscribing witnesses, this 5th day of February, 1904.
